First birding day in a while!

An open space with a sign that reads "Keep physical distancing"

After almost six months of confinement due to the sanitary emergency, I finally went out to have a birding day, searching for shorebirds in order to participate in the World Shorebirds Day.  The high tide was quite early, so I started with the first lights.  My plan was to visit several places along the waterfront of Panama City, following the tide.  With the water level high, I chose a rocky spot that provide resting sites for tired shorebirds when they are not foraging in the mudflats.  As expected, I found some loose flocks with some of the most common species, plus rocky shores specialists, like Ruddy Turnstones and Surfbirds.  However, they were too distant for decent photos, so I concentrated my shots in some nearby targets, like the groups of Least, Semipalmated and Spotted Sandpipers that were checking the small puddles on the rocks.

After 30 minutes carrying my backpack, camera, lens and binoculars, I realized that I was exhausted!  Certainly, the sedentary routine of my confinement had something to do with that!  The air conditioner of my car was huge relief... but I had no time to waste, the tide was retiring, exposing the mudflats of my next stop: Costa del Este.  The wetlands of the Upper Bay of Panama are of hemispheric importance for the migratory shorebirds.  Millions of birds use the area during their annual paths, the reason why Panama Audubon Society has worked incessantly in protecting the site, monitoring its birds and doing environmental education in the surrounding communities... and Costa del Este is one of those communities.  From the lookout with interpretative signs depicting shorebirds, I was able to scan the extensive mudflats at the mouth of the Matía Hernández river, adding Black-necked Stilts, Black-bellied Plovers, Greater Yellowlegs, Short-billed Dowitchers and, specially, thousands of Western Sandpipers, although widely dispersed.

After my short 30-min stop at Costa del Este, I went to a nearby site for a change.  If you want to see a greater diversity of species, then you need to visit different habitats, so I went to a grassy meadow with artificial ponds, known as MetroPark.  The pond had Wattled Jacanas, Black-necked Stilts and both Lesser and Greater Yellowlegs, while the grassland had Whimbrels and many Southern Lapwings.  I was not the only human being at the site, several people use the open spaces to work out and breath "fresh air"... of course, following the sanitary recommendations, as explained in the multiple signs all over the place (as you can see in the first photo).  My last stop was, again, a different habitat... the only sandy beach of the waterfront, right at the Panama City's coastal belt, by the mouth of the Matasnillo river.  As expected, it produced my only Sanderlings of the day.  Two pale birds were agitatedly feeding in the sand, going forth and back with the waves.  By that time, the tide was low enough to take a break until the next high tide, in the afternoon.

For the second round, I joined my friends Rosabel Miró, Venicio "Beny" Wilson and Aitor Gonzalo, who were also participating in the World Shorebirds Day.  We were after an species that occurs near the city only at one reliable site at the West Bank of the Panama Canal.  The combination of sandy and rocky beaches with tons of bivalves and other mollusks to feed is ideal for the American Oystercatcher.  we knew a place where they breed, so we went there and were rewarded with a pair of vocalizing birds that flew right above us... what a sight!

American Oystercatchers

Pitifully, we were not able to find two plovers species that are also found at that habitat: Collared and Wilson's Plovers, which are also localized near the city.  To take advantage of the few hours of light left, we swiftly moved back to Costa del Este, where the tide cornered the birds in a section adjacent to the mangroves, where these birds spend the night.  We added Marbled Godwit to our checklists, but were impressed with the thousands of peeps present at the site, mostly Semipalmated Plovers, Western and Semipalmated Sandpipers.

Almost at night, we left the mangroves (and the mosquitoes), our final count was more than 5000 peeps in that little corner of mangroves.  At the end of the day, I managed to record 19 different species of shorebirds at, or near, Panama City.. an excellent number!  So tell me, how was your World Shorebirds Day?    

Shorebirds all around!

When Osvaldo Quintero and I arrived to days ago to the entrance gate of Finca Bayano, to the east of Panama City, the picture was not good... storm clouds were covering the entire place and the overcast day was cold and windy.  It didn't take long before we had to shelter inside the car and wait for the rain to stop.  By that time we only had seen some herons and Wattled Jacanas, but not a single shorebird... and we were after a special one, the Buff-breasted Sandpipers reported twice at the site earlier this season.

Eventually, the rain stopped enough to start to watch birds.  The place was flooded and wet... but it was just perfect for shorebirds... they started to appear all over the place: on the road, at the fields, flying overhead... everywhere!  The most common were the peeps, with Least and Western Sandpipers as the most conspicuous, but also with some Semipalmated Sandpipers as well.

Least and Western Sandpipers

While watching them, we started to notice larger shorebirds mixed in.  Most of them were Pectoral Sandpipers but, eventually, we noticed one bird with yellow-buffy tones and yellow legs... it only stayed enough for a couple of shots, but it proved to be the only Buff-breasted Sandpiper of the day!

Pectoral Sandpipers

Buff-breasted Sandpiper

The Buff-breasted Sandpiper is a rare passage migrant in Panama, with only few reports each fall (almost none in spring).  This was just the second time I see this species, and was a life bird for Osvaldo!  However, it was not the main highlight of the day.  Soon we realized that it was about to be a unique trip... other rare passage migrants showed up as well: several Stilt and White-rumped Sandpipers were around allowing photos.

Other not-so-rare-but-pretty-uncommon species showed up well too, including a pair of confident American Golden-Plovers and, as a photographic highlight, I have to mention the Wilson's Snipes.  They are common winter visitors but you not often see them so close!

Nice collection of birds eh?  Oh yes, and there was also the first-record-for-Panama thing... well, YEAH!  A bird ever recorded in Panama... about the same size of the Pectoral Sandpipers, but with contrasting chestnut crown and white eye-brow... but most important, buffy breast with almost no streaks... here is the photo that I added to my eBird checklist:

SHARP-TAILED SANDPIPER... WOW!  An Asian breeder way out of route!  It is still pending review, but if accepted by the local Birds Records Committee, it could be the first documented one for Central America!  Now that is what I call a terrific day!

Today is World Shorebirds Day!

All over the world we celebrate today the shorebirds!  Delicate in appearance but certainly some of the most strong flyers in this planet, many shorebirds species make, twice a year, long-distance migrations, some of them traversing more than 15,000 miles annually!  Being birds that visit whole continents, it is important to join efforts not only to protect their breeding grounds, but also their wintering grounds and stopover sites along the migration routes.

The Upper Bay of Panama, a site of hemispheric importance for shorebirds survival

That's why the World Shorebirds Day celebration was created... to raise GLOBAL public awareness about the conservation of, and research about, shorebirds (you can read more at the World Shorebirds Day Official Website).  During this past weekend, I participated in the global shorebirds counting among other members of the Panama Audubon Society in two sites of the Upper Bay of Panama: Costa del Este and Panama Viejo.  In spite of the season (in Panama, the migration season is just starting), the numbers present in both site were impressive... as usual!

Peeps in Costa del Este (September 3rd, 2016)

The most abundant species were the peeps... with Western and Semipalmated Sandpipers as the most common.  ID is difficult of course in their basic plumages... but in both sites you can get them side-by-side, making the whole thing a little bit easier.

Western and Semipalmated Sandpiper in Panama Viejo (September 4th, 2016)

The approximate count was close to 8000 peeps in Costa del Este,  a low number compared to other seasons.  We entered our records into eBird (in two checklists http://ebird.org/ebird/view/checklist/S31398127, http://ebird.org/ebird/view/checklist/S31419633) thus joining hundreds of other birdwatchers around the world.  Panama shorebirds were well represented, with 14 species recorded by me in both sites (12 species shared by both sites, plus another one in Costa del Este -Least Sandpiper- that I didn't manage to see, but recorded by other observer).  Here are some of them:

Greater Yellowlegs in Panama Viejo (September 4th, 2016

Semipalmated Plover in Panama Viejo (September 4th, 2016)

All these species are regular and quite common in Panama; however, we also found a Long-billed Curlew in Panama Viejo.  This one is considered a vagrant in Panama, but one individual had spent many winters in the mudflats of Panama Viejo (but is difficult to find).

Long-billed Curlew (September 4th, 2016)

Almost all the shorebirds recorded were long-distance migrants, but we also saw three resident species: Southern Lapwing, Wilson's Plover and Black-necked Stilt.  The first one is common all over Panama, while the other two breed in small colonies in just few sites in the country.  Each winter, their populations increase with migratory individuals from other latitudes.

And you, how do you spent your World Shorebirds Day?

World Shorebirds Day. Part II

Due to technical problems, I was unable to post this story before (as many others as well).  Last weekend, many countries celebrated the World Shorebirds Day, and Panama was not the exception.  Many official institutions and NGOs, organized by the Panama Audubon Society (PAS), gathered in Costa del Este (Panama City) at high tide last september 6th to participate in the Shorebirds Challenge.  After the event, some PAS members stayed to count shorebirds... I joined them the next day.

Shorebirds in Costa del Este

After last sunday's coastal cleanup event in Costa del Este, I joined Rosabel Miró, Michele Caballero and others at shore in the mouth of the Matías Hernández river... the impressive diversity of shorebirds species amazed us... just the photo above shows seven shorebirds species plus Laughing Gulls and a Great Egret... can you ID these species?  Little after I took the above photo, we started to see the flocks of peeps approaching.

Mostly Western Sandpipers

Western Sandpipers

Thousands of peeps, mostly Western Sandpipers, started to appear in the exposed mudflats and in the mangroves.  These birds use the Upper Bay of Panama as feeding station during their passages or as winter grounds.  In an effort to better understand these movements, many of these birds have been ringed with flags of specific colors for each country (more about it in this post).  Earlier that day, Yenifer Díaz and Michele saw briefly one of these birds for short time but they were not able to read the characters in the flag.  Then, through the scopes, we managed to find three different birds with rings and flags.  Rosabel got this distant photo:

Banded Western Sandpiper.  Photo by Rosabel Miró

This particular bird had a muddy flag.  The other two birds had legible flags.  Both were banded almost in the same site last season earlier this year.  Simply amazing!  Only some 200 birds were banded... and we saw three of them!  However, more strange was this little guy:

Semipalmated Sandpiper

As you can see, this is a Semipalmated Sandpiper (notice the short bill)... a leucistic individual (a condition characterized by reduced pigmentation).  Is the first one I ever see... but the web is full of galleries showing these aberrant beauties.  In total, we saw 16 shorebirds species (plus another species seen the previous day)... and three banded ones!

Tight together by the tide

Last friday 16-feet tide was high enough to push all the shorebirds of Panama Viejo to a tiny piece of beach close to the road. When I got to the place, it was raining so I started to watch them with my binoculars, waiting for the rain to stop. I noticed a plump-shaped shorebird accompanying the flock of peeps, evidently larger than them and looking quite similar to a dowitcher, except for its short bill... it also behaved different. A closer look revealed it to be a basic-plumaged Red Knot, which is not often found there. The rain stopped so I left the car and started to approach the birds. The knot did not stay, but all the others shorebirds did, including the flock of Short-billed Dowitchers. I usually don't have these close encounters with the dowitchers, so I took all the photos I could, including the molting individual that still was exhibiting some juvenal feathers at the coverts and the tail (the third photo).But definitively, the main show was protagonized by the three peeps species. I have to say that in Panama, these birds show their alternate plumage just for a brief period of time. The Least Sandpiper is, perhaps, the most easily identified, with its yellow legs, the thin bill and darker back. The size per se is not a good field mark as you can see in the next photo. Also, they usually like to wander close to the grassy coast and to the mangroves, instead at the extensive tidal flats like the other two species.In basic plumage the Western and Semipalmated Sandpipers are very difficult to distinguish. The main field marks are bill lenght and shape. Other field marks, like body shape, grade of facial contrast and vocalizations are not easy to determine under usual viewing conditions. Even with close and careful observations, many sandpipers will be left unidentified. I can id for sure the extremes... that is, long-billed females Westerns' (almost always with an evident dropped tip of the bill) and short, straight-billed males Semipalmateds'. For example, the next three photos are Western Sandpipers (the last two photos of a juvenile molting into basic-plumaged adult?).And the next ones are of a Semipalmated Sandpiper.Bear in mind that both species can show the rufous tinge to the scapulars, so it is not a good field mark in Panama. That day, it seemed that most of the peeps present were Western Sandpipers.
The peeps were all tight together in the same flock, with the dowitchers and some plovers, specially Wilson's and Semipalmated Plovers, with few basic-plumaged Black-bellied Plovers among the multitudes.

In general, the big shorebirds were apart of the peeps. The exception were the Willets... they looked immense compared to the peeps surrounding them.

But my favorites were the Marbled Godwits. That bubblegum-pink bill is unreal.

Well, a typical day at the Panama Viejo's mudflats!

Shorebird close to home

I almost forgot how much I like to watch shorebirds at the Panama Viejo / Costa del Este mudflats. The upper Bay of Panama is an hemispherical important site of the route of migrating shorebirds from the Artic to South America (and beyond!). Each year, hundreds of thousands peeps and other shorebirds make an stop to refuel, or to stay all the winter. But the more important fact is that it is right by the city. I went to Panama Viejo this morning, taking advantage of the early high tide, and found tons of cooperative shorebirds. If they were cooperative? Well, just check out these photos (they were all taken today):The Semipalmated Sandpipers were the most common peeps, outnumbering the Western Sandpipers.This absolutely gorgeous juvenile Least Sandpiper allowed some photos. There were many adults as well. The Spotted Sandpiper is the most widely distributed shorebird in Panama, found almost everywhere if there is water around. I still need a photo of one really "spotted".If you see a dowitcher in Panama, it certainly is a Short-billed Dowitcher. Several flocks, including birds wearing breeding and non-breeding plumages, were present. The pale, bigger bird accompanying them in the second photo is a Willet

The strong, colourful and contrasting pattern of the Ruddy Turnstone is amazing. This bird rules!

These flying birds are Surfbirds. I counted at least 40 birds in that single flock!

The Whimbrel is found year-round in Panama, but definitively is more common during the winter. At least 15 birds were scattered at the mudflats.Contrary to the Whimbrels, there is usually only one Long-billed Curlew in these mudflats. Patiently, surely you'll find it, usually feeding independently of other big shorebirds.The plovers were well represented. From top to bottom, these are: a pair of Semipalmated Plover (migrant, but the most common plover in Panama), Wilson's Plover (resident, this seems to be a juvenile) and Collared Plover (resident -and cute-, this also seems to be a young bird). I also saw many Black-bellied Plovers and three Southern Lapwings in the area (but they were not close enough). Add to this list the American Golden-Plover recently reported at Costa del Este by Carlos Bethancourt and you will get the picture of how special is this place!

I tried to find the American Golden-Plover at Costa del Este, but when I got there, all the birds were too far away in the mudflats, so I didn't find it. Anyway, a Franklin's Gull wearing most of its breeding plumage was a great consolation prize.
